ABC Institute of Research has sensitive information that needs to be protected from its rivals. The Institute has collaborated with XYZ Inc. to research genetics. The information must be kept top secret at any cost. At ABC Institute, the researchers are unsure about the type of key (asymmetric or symmetric) to use. Please formulate a possible solution, and describe the advantages and disadvantages of any solution employed.

According to my research symmetric and asymmetric have pros and cons which are the following:

Symmetric key encryption is also known as secret key and private key. However in this type of encryption the sender and receiver share the same key, which is used to encrypt and decrypt messages. According to my research the sender and receiver have to specify the key in the beginning and then they can start encrypting or decrypting using the same key. Some advantages are that encryption is easy to carry out. However users have to share the secret key and then begin to encrypt and decrypt messages. Another big plus is that when you need to encrypt or decrypt your own files on a message or files, there is no need to create different keys. We have to remember that symmetric key encryption is faster than asymmetric key encryption. The reason because is faster is because single key encryption does not require a lot of computer memory compared to a public key encryption. If the key is compromised, only the messages between a particular pair of sender and receiver will be affected. Some disadvantage is the need for secure channel for secret key exchange. Another issue is that when you need to communicate with every different party you need to create a key. This creates a problem with managing and ensuring the security of all these keys. Since the key same key is used by every body you cannot verify is the user that make changes. This may be a problem if there is a dispute.

Meanwhile Asymmetric Also known as public key. This method need two keys which are a public key and a private key. The public key is used to encrypt a message by anyone wants to send a message to the person that the key belongs to. The private key is kept secret and is used to decrypt received messages. Some advantages of this method are that it solves the problem of sharing one the key for. Everyone public keys and private keys are kept secret. Public key encryption allows digital signatures to enables the recipient of a message. This helps know if the message is truly from a particular sender. A digital signature in public key encryption helps us detect if the message was altered. A big plus is that digitally signed message cannot be alerted without invalidating the signature. Unfortunately there are some disadvantages. For example, No one can be one hundred percent sure that a public key is from that person so everyone must verify that their public keys belong to them. A big disadvantage is that public key encryption is really slow compared to symmetric encryption. Is not very efficient on decrypting bulk messages. Also it requires a lot of memory compared to single-key encryption. If a hacker cracks a person's private key, his entire messages can be read.

In conclusion I will recommend Symmetric key encryption. The reason I choose symmetric key is because when you need to encrypt or decrypt your own files on a message or files, there is no need to create different keys. Symmetric key encryption is faster than asymmetric key encryption. Also you only create one key so without that key you cant do anything and is very useful for top secret information.
